How to Repair a Concrete Seawall

If you own a property along the coast in Texas, chances are you have a seawall to protect your land from erosion. These structures can be made of various materials, but concrete is a popular choice due to its durability and strength. However, even concrete seawalls can become damaged over time due to the harsh saltwater environment and the constant pressure from the waves. When this happens, it’s important to address the issue and repair the seawall to prevent further damage.

Here is a step-by-step guide on how to repair concrete seawall in Texas:

1. Assess the Damage

The first step in repairing a concrete seawall is to assess the extent of the damage. This will help you determine the necessary materials and tools needed for the repair, as well as the overall cost of the project.

Look for cracks, chips, and other signs of damage. You should also check the base of the seawall for any erosion or instability. If the damage is extensive, it may be necessary to hire a professional to help with the repair.

2. Clean the Area

Before starting the repair, it’s important to clean the area around the damage. Remove any loose debris and use a pressure washer to remove any dirt or salt build-up. This will help ensure that the repair material adheres properly to the concrete.

3. Repair Cracks and Chips

For small cracks and chips, you can use a concrete repair compound to fill in the damaged areas. Make sure to follow the manufacturer’s instructions for mixing and applying the compound. Use a trowel or putty knife to smooth the surface and remove any excess material.

For larger cracks, you may need to use a concrete patching material. These come in either a wet or dry form and are applied in a similar manner to the repair compound.

4. Replace Damaged Sections

If a section of the seawall is severely damaged or has collapsed, it may need to be replaced. This is a more complex and time-consuming repair that should be done by a professional.

5. Protect the Seawall

Once the repair is complete, it’s important to protect the seawall from further damage. This can be done by applying a concrete sealer to the repaired areas. This will help prevent saltwater erosion and protect the concrete from the harsh coastal environment.


Repairing a concrete seawall in Texas requires careful assessment of the damage, cleaning the area, filling in cracks and chips, and possibly replacing damaged sections. It’s important to address any issues with your seawall as soon as possible to prevent further damage and ensure the protection of your property. Hiring a professional, such as FoamWorks for this type of project may be necessary for such extensive repairs.
